The design is based on the design feature of closer contact between valve plate and valve seat under medium pressure. The higher the medium pressure is, the better the tightness is,So its sealing is higher than ordinary butterfly valve. As shown in the figure on the right, no matter which direction the valve is under force, the valve is in both positive and negative directions,Both the valve plate and the valve seat can be tightly connected by using the medium pressure (shown by the red arrow)
Product design and manufacturing characteristics
1. Double eccentric design, longer product life.
2. It can withstand 10o times / minute closing and has strong wear resistance.
3. A combined PTFE water seal is installed between the valve rod and the valve body, and the pressure plate is designed to tighten the axial direction seal. making it more reliable.
4. The valve seat adopts standard parts. After RTFE valve seat is worn, the customer can replace it by himself
5. After the pin material of butterfly valve is quenched and tempered, it has high strength and
corrosion resistance. The connection is more secure and stable.
6. The valve body and valve plate are manufactured by precision 4-axis CNC milling with high precision
